The Pioneer of Bridal Jewelry: Ginza Diamond Shiraishi

Ginza Diamond Shiraishi celebrates 31 years since its founding. It is Japan's first* bridal jewelry specialty store.

Established in 1994 on Ginza's main avenue, as of July 2026, it operates 69 stores across Japan, making it the largest bridal jewelry brand in the country. Guided by the vision of 'diamonds for every bride,' the company delivers high-quality diamonds.

The diamonds selected here are not only evaluated by the well-known '4C' quality standards but also prioritize 'brilliance'—the essential quality that makes a diamond truly beautiful. These are diamonds that radiate exceptional sparkle. Only at Ginza Diamond Shiraishi can you pair your chosen diamond with your favorite ring design.

With over 18,000 loose diamonds and more than 700 ring designs always available, we answer the wishes of countless brides who desire 'one-of-a-kind, personalized rings.'

The concept of wearing engagement rings (engagement rings) and wedding rings (wedding rings) together as a 'set ring' was also pioneered by the industry. Smooth wearability and beauty from the side are further enhanced by meticulous handcrafting.

Additionally, the lifelong warranty and after-sales service reflect our commitment to rings that accompany couples for life. All of this embodies our heartfelt desire and wish to 'support every couple and shape their happiness.' This has been our mission, and it always will be.

Ginza Diamond Shiraishi will continue to be a brand that walks alongside every couple’s life journey.

The Appeal of Diamonds Offered by Ginza Diamond Shiraishi

Quality Offering Diamonds with the Highest Rating: Ultimate

* Saline Light Reports are not issued for certain diamonds, such as those under 0.25ct, color H or lower, or clarity SI1 or lower.

Going beyond the traditional '4C' diamond quality evaluation, we conduct the 'Saline Light Report,' which specifically assesses a diamond’s brilliance. Even among rough diamonds selected from renowned global polishers, those achieving the highest 'Ultimate' rating are rare. Yet, over 99% of the polished diamonds procured by Ginza Diamond Shiraishi have been verified to achieve this top-tier 'Ultimate' rating.

Sourcing and Selecting High-Quality Diamonds from Around the World

Driven by the desire for customers to own pure, untouched 'virgin diamonds' that have never passed through anyone else’s hands, Shiraishi does not handle recut or reused diamonds. By directly and consistently sourcing the world’s most beautiful diamonds ourselves from the global market, we achieve fair pricing and deliver diamonds whose quality surpasses even what certification reports can convey.
